The Centauress standing there looking at something and moving her arms to various positions is possibly from Winsor McCay's The Centaurs, a partially lost cartoon. If it is, you may have discovered a previously unknown portion of the cartoon, Milton. Good job! I subscribed.
It's from a Swedish cartoon by Viktor Bergdahl called CAPTAIN GROGG AMONG OTHER STRANGE ANIMALS. It's been dated as 1923. Thanks for Subscribing! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1zWpTHkULnA.html
